Polanco is out of the lineup for Sunday's game against the Astros.

The switch-hitting Polanco still isn't fully comfortable batting as a right-hander while he's been managing a sore side for much of the season, so the Mariners will hold him out of the lineup for a second straight day while the Astros send another southpaw (Colton Gordon) to the bump. Mitch Garver will replace Polanco as Seattle's designated hitter.

The Blue Jays placed Heineman on the 7-day injured list Sunday due to a concussion.

Heineman took a couple foul balls off his catcher's mask during Thursday's game against the Padres and reported concussion symptoms Saturday, so he's now in the concussion protocol. Ali Sanchez was added to the big-league roster to serve as Toronto's backup backstop while Heineman is out.

The Rangers placed Pederson (hand) on the 10-day injured list Sunday.

Pederson fractured his right hand when it was hit by a pitch in Saturday's 10-5 loss to the White Sox. The veteran slugger said after the game that he was given a six-week estimate for a return from the IL, so he could be out of action until around the All-Star break. Prospect Alejandro Osuna was called up from Triple-A Round Rock in a corresponding move and could end up serving as Pederson's primary replacement in the lineup against right-handed pitching, either at designated hitter or in an outfield spot.

Manzardo will start at first base and bat fifth in Sunday's game against the Tigers.

The left-handed-hitting Manzardo was initially scheduled to receive the day off, but he'll end up having to face southpaw Tarik Skubal after the Guardians made Carlos Santana (leg) a late scratch. Manzando has a surprising 1.139 OPS against southpaws this season, albeit in only 34 plate appearances.

Bell is out of the lineup for Sunday's game against the Giants, Bobby Blanco of MASNSports.com reports.

The switch-hitting Bell has produced an abysmal .065/.216/.129 slash line over 37 plate appearances against lefties this season, and the Nationals seem content to treat him as a platoon player for the time being. He'll remain on the bench for the second day in a row as the Nationals face off against another Giants lefty in Robbie Ray.

Manzardo is out of the lineup for Sunday's game against the Tigers.

Manzardo has turned in a 204 wRC+ in a small sample of 34 plate appearances against southpaws this season, but the Guardians will still be selective with his usage versus same-handed pitching. With reigning Cy Young Award winner Tarik Skubal on the bump for Detroit, Manzardo will head to the bench and allow Jose Ramirez to get a partial rest as the designated hitter.

Grichuk went 2-for-4 with a home run and two RBI in Saturday's 6-5 loss to the Cardinals.

Grichuk tied the game in the fifth inning with his second homer of the season, and both have come in his last seven games. He typically plays against left-handers only and is a better fit for fantasy leagues with daily transactions. Grichuk mashed southpaws last season but got off to a middling start in 2025 before making a bigger impact lately, going 7-for-17 (.412) with a 1.235 OPS over his last seven contests.

Schwarber went 2-for-5 with a home run, a double, a walk, three RBI and two runs scored in Saturday's 9-6 extra-innings win over the Athletics.

Schwarber put the Phillies ahead 4-3 with a solo shot in the sixth inning, and he added a two-run double in the 11th to give them the lead for good. With the long ball, Schwarber has retaken the National League lead with 18 homers through Saturday's action. The slugger hadn't logged multiple hits since May 11 in Cleveland, and he now has four homers and eight RBI over his last 12 contests. He's slashing .255/.397/.580 with 40 RBI, 40 runs scored and four steals over 52 contests this season.

Santander went 2-for-2 with two walks in Saturday's 3-1 loss to Tampa Bay.

Santander was not in the Blue Jays' starting lineup for two straight games due to a left hip issue, but he was back out in right field for Saturday's contest. He reached base safely in all four plate appearances but wasn't brought home to score as the Jays' offense was limited to just one run. Santander has struggled at the plate this season but has been more effective since the beginning of May, slashing .245/.344/.377 with two home runs and six RBI in 61 plate appearances.

Pederson fractured his right hand during Saturday's 10-5 loss to the White Sox and said after the game that he expects to be out for around six weeks, Shawn McFarland of The Dallas Morning News reports.

Pederson suffered the injury when he has hit by a Bryse Wilson pitch in the fourth inning. He initially stayed in the game and came around to score three batters later, but he was replaced by Kyle Higashioka in the fifth. The injury is an unfortunate setback for Pederson, who had shown improved production at the plate in recent weeks after getting off to an ugly start to the season. He's still batting just .131 with two home runs over 145 plate appearances, though he had gotten on base at a .269 clip thanks in large part to his strong 14.1 percent walk rate.
